Froeschke ,   et al. | January 7, 1997 |
A mechanism for making granulated material from a viscous substance includes a vessel charged with the substance and having a discharge opening arrangement for discharging the substance onto a cooling surface. A belt travels across the vessel, the belt having openings arranged to periodically come into alignment with the discharge opening arrangement to allow the substance to fall onto the cooling surface. The discharge opening arrangement comprises a plurality of rows of discharge openings. Each row extends transversely of the longitudinal direction of belt travel, and the rows are spaced apart in that longitudinal direction. The vessel openings of each row are offset in the transverse direction with respect to the vessel openings of other rows. A collection arrangement collects residual substance falling from the belt and returns the substance onto the belt at a location upstream of the vessel.
